Laplace's Law - the greater the radius of a cylinder, the greater the wall stress. More formally, stress = Pressure × radius / thickness as long as thickness is less than 10% of radius.

To generate a very high force, you would need very high pressure and radius, which in turn means you either need very thick walls or very strong material to prevent failure. Neither is impossible but both are expensive.
